Hi,
Seems to me this article is missing any discussion of carburettors, turbochargers, superchargers, fuel injection and so forth. There's no fuel going into our ICs! WolfKeeper
I have a question:
When you press on the accelerator pedal of a petrol engine, you open the throttle and allow more fuel/air mixture to enter each cylinder. Therefor the harder the acclerator is pushed, the more volume enters the cylinder; and thus the compression is increased, yes?
The average compression ratio of a petrol engine is about 10, but is that at full throttle. Is the compression much less when the engine is idling?
On the other hand a diesel engine is only controlled by how much fuel is injected , so the compression ratio is always about 20.
However it gets much more confusing when a turbo is added =(
The compression ratio remains the same no matter what the throttle setting is but the compression pressure varies with throttle settings . Usually on petrol engines with 10 to 1 compression ratio the open full throttle cranking start speed (1000RPM) is about 150 to 220 PSI but at part throttle it could be as low as 40 PSI. malbeare 20/5/2007
No mention of the swashplate configuration is listed in the current article (31 July 2007). http://en.wikipedia.org/wiki/Swashplate_engine Swashplate Engine
Hello, I am not a regular contributor to wikipedia, so forgive any buffoonish errors I make in the following.
In revision 413119031, user Twexcom removed the clause "the ICE delivers an excellent power-to-weight ratio with few disadvantages" from the sentence "Powered by an energy-dense fuel (which is very frequently petrol, a liquid derived from fossil fuels), the ICE delivers an excellent power-to-weight ratio with few disadvantages."
It seems clear that this was an attempt to remove the potentially controversial claim that internal combustion engines have "few disadvantages," but what remains is the fragment "Powered by an energy dense fuel."
I considered simply adding "...the ICE delivers an excellent power-to-weight ratio," but given that this error has persisted for nearly two years, and that even this reduced version of the sentence contains the value-laden word "excellent," I decided to post to the talk page and let the wiki natives decide how to proceed.
Thanks for all y'all do.
https://en.wikipedia.org/?title=Internal_combustion_engine&oldid=920303500 introduced a postulation that internal combustion engines are not heat engines, without a citation, or an explanation which is readable to someone who has not continued education beyond secondary school. Erkin Alp Güney 20:15, 10 October 2019 (UTC)
The article on the Internal Combustion engine cites Étienne Lenoir (1860) and Nicolaus Otto (1876) as THE INVENTORS of the Internal combustion engine. However, the internal combustion engine was invented much earlier by Isaac de Rivaz (1806). And that engine was very modern with electric ignition (AND HYDROGEN fuel). This facts in your article somehow went almost completely hidden. I think it is not only unfair but slightly dishonest too. Regards 27.32.23.226 ( talk) 09:06, 3 June 2021 (UTC)
"ICEs are typically powered by fossil fuels like natural gas or petroleum products such as gasoline, diesel fuel or fuel oil."
The sentence structure makes it sound like there are two typical types of fuel: fossil fuels (e.g. natural gas) and petroleum products (e.g. gasoline, diesel fuel, or fuel oil). Is there a better way to word it, so that the sentence structure makes it clear that natural gas and petroleum products are both fossil fuels? I can't think of one. 175.39.61.121 ( talk) 01:35, 15 September 2022 (UTC)
